MORGAN LAVERING AND ELI H. ANSPAUGH, OF COLUMBIA CITY, IND.

GRAlN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 346,822, dated June15,1886.

Application filed June 10, 188i. Serial No. 134,482. (No model.)

To all whom it may concern.-

Be it known that we, MORGAN LAVERING and ELI H. ANSPAUGH, citizens ofthe United States, residing at Columbia City, in the county of \Vhitleyand State of Indiana, have j ointly invented anew and useful Improvementin Grain-Separators, of which the following is a specification.

Our invention relates to the means employed for separating the thrashedgrain from the straw and chaff; and the object of our invention is toeffect such separation thoroughly, expeditiously, and economically. WVeattain this object by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a detailed side and top View inperspective of the entire machine. Fig. 2 represents a grain cell-head.Fig. 3 represents a cell-bar with a cell-head attached to each endthereof. Fig. 4 shows a grain-cleat, and Fig. 5 shows a grain-stop.

Similar letters refer to similar parts throughout the several views.

In Fig. 1, A represents the framework, different portions of whichsupport the operative parts of the machinery.

B is the first grain-web, made of canvas cloth, and to it are attached,transversely and on edge, the bars F F, each one of which has a cellheadattached to each end, as shown in Fig. 3.

D shows the second grain-web, to which are attached, transversely and onedge, the graineleats P P, Fig. 4, and the grainstops R B, Fig. 5.

E, Fig. 2, is a cell-head shown separately from the bar to which itbelongs.

F is the bar connecting the two cell-heads.

H designates short back boards, to which the cell-heads are secured inpairs at a sufficient distance apart to allow the ends of the bars F tobe received between them, the back boards, H, being also secured to thebars F.

.VVe secure the cell-heads to the cell-bars by nailing or otherequivalent means.

K represents the cells or spaces between the bars after they arefastened to the web B. Motion is given to web B through the pulleys 1and 1 attached to the outer ends of suitable shafts, around which theweb is drawn.

L is a beater (revolved through pulley 4) at the upper end of B.

N N are slats fastened to the bands N N of the straw-carrier S, whichruns upon shafts propelled through pulleys 3 and 3.

O O are the two sets of arms of the agitator, connected by shaft 0revolved by means of a pulley.

T T are the spaces or grain-cells between the slats P P.

W indicates the point at which the thrashed grain, straw, and chaff aresupposed to first strike the grain-web B.

X is a beater placed at the extreme outer end of carrier S.

Pulleys 2 and 2, acting through the shafts to which they are attached,give motion to the second grain-web, D.

In all operating parts of the machine the di reetions of the differentmotions are indicated byarrows. The belts for propelling the variouspulleys are omitted, for the reason that their application and use areobvious and well understood.

The practical operation of our improved grain separator is substantiallyas follows: The thrashed grain, straw, and chaff coming out of thethrasher strikes web B at W, and, entering the cells or spaces K Kbetween the bars F F, is conveyed forward and upward until it passesover the upper end of grainweb 13, where the grain falls down to secondgrain-web, D, at about the point indicated by V, the straw being caughtby the beater L and thrown over on the carrier S,which conveys it towhere it is caught by beaterX and thrown over to the point Z, where itpasses to another straw-earrier. (Not here shown.) When the grain fallsto the second web, D, as mentioned, it enters the spaces or cells T Tbetween the slats P I, and is conveyed to the outer end of saidweb,where, at the point Y, it falls off upon the,riddles,whicl1 are nothere shown. By the use of this second grain-web, D, we save from loss agreat amount of grain that is scattered and wasted in using ordinarymachines.

The use of the straw-carrier S in the manner shown, and the use of theagitator O O, with its curved arms striking on the under side of theupper portion of carrier-bands N N efi'ect a more thorough separationand saving of grain than is possible under the old methods.

The formation of the cells K K onweb B will ICO be readily understood bya reference to Figs.

2 and 3, from which it is evident that if we attach two or more of thedevices shown in Fig. 3 to the canvas closely together, side by side,oneor morecells or boxes will be formed,

of which the sides will consist of the bars FF,

the ends of the cell-heads E E, and the bottoms of the canvas of thewebB. To form the cells or spaces T T on the second grain-web,

D, the slats P P are attached, as before stated,

and the stops R Rattaehed to the web between the slats, as shown.Cell-heads E E and stops R R are made wedge-shaped and sloping inward,so as to cause the graimto always roll I 5 toward the center of eachweb. The width of the cells or spaces K K can be regulated by increasingor diminishing the length of the cell-heads. The width of spaces T Tdepend on the number and widths of the stops R R,

attached to the canvas between the slats. The

bars F F and slats P P are made as long as the widths of the grain-websto which they are fastened.

- It is obvious that-our improved grainseparater can be made of anydesired'size and capacity that may be demanded.

While we have described the entire machine at length,we wish it to beunderstood that the invention rests in the peculiar construction of thebelts l3 and D, and in the combination thereof with the straw-carrier Sand beater L.

What we claim as our invention, and desire to secure by Letters Patent,is

1. In a grain-separator, the combination of a belt or web, B, arrangedat an incline and equipped with'cfoss-bars and cell-heads, and a beaterarranged at the end of said web,with a straw-carrier, S, arrangedto takethe straw from the beater, and a second belt or Web, D, arrangedhorizontally beneath the beater and provided with cells formed by slatsP P and inclined or beveled stops R R, the whole arranged for jointoperation, as set forth.

2. In a grain-separator, a grain web or belt provided with graincellsformed by transverse slats and wedge-shaped grain-stops fastened to thegrain web or belts, substantially as described and set forth.

8. The combination,with the endless web of canvas, of the wedgeshapedblocks E, secured in pairs to back boards at a distance apart, and thecross-bars F, arranged with their ends between such pairs ofwedge-shaped blocks, and the whole secured in regular series to thecanvas, to form the web or belt B, as set forth.
